Cleaning condensate pan/drain

Been having a smell problem when the AC starts up. I've narrowed it down to likely a mold issue either in the drain pan or the condensate line. I've poured bleach down the condensate line which does help, but now I'm wondering might be lurking in that pan getting blown around the house and not realizing.

My problem is that the coils are inside a duct with no access panels. It's basically a 24" duct that's screwed into the furnace and to the main trunk above. I've stuck my hand into one of the main trunk branches and took a picture downward to the coils and they look reasonably clean. I'm assuming there's some kind of pan under each?

Any suggestions? I can post a pic if I'm not making sense.

Thanks,
Mike

I never could figure out how inspectors pass this.

The metal duct covering your uncased evaporator coil may have to be cut to gain access to the coil. This will run the risk of damaging the coil.

Once you remove the metal covering the coil, it isn't much different from a standard cased coil.



Removing the blower and shining a flash light up the furnace would allow you to see the dirty side of the coil.
